GAS-BURNER.

Specification of Letters Patent.

Patented Apr. 1,1919.

Application filed December 20, 1918. Serial No. 267,680.

To (ZZZ whom it may concern Be it known that I, HERMAN C. SIEBERT, a citizen of the United States, residing in the city of South Bethlehem, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Burners; and I do hereby declare the followingto be a full, clear, and exact description, such as will enable others skilled in the art to which it appei'tains to make and use the same.

My invention relates to a gas burner that is particularly adapted for use in connection with the combustion of blast furnace and producer gases, although it may be used for other combustible gases, as may be readily understood.

My burner consists ess ntially of a pipe which may be of rectangular or other section, with a connection thereto to supply gas to said pipe, and in the interior thereof I provide a tubular construction with open ends, one of which connects with the air to supply air for combustion. The gas, therefore, passes around the outside of the internal conduit between it and the walls of the outer pipe or casing, as the air is supplied to the interior pipe, being, therefore, entirely surrounded by the gas at its outlet end in such a way that it will mix with it thoroughly for the purpose of combustion. The inner end of the air-pipe is provided with hinged doors or flaps adapted to. be closed together or opened to any desired extent, and is provided with a convenient op"rating handle for this purpose, the end of which projects outwardly from the constru tion and is provided with means for locking same in place. These doors, therefore, regulate the supply of air necessary for perfect combustion and may diminish the air 'supply by partially closing them together, or may diminish the gas supply by opening toward the walls of the gas pipe or conduit and the operating doors or wings in any position always form an air opening concentric with the outer gas pipe and thus provide a uniform and thorough mixture of gas and air. 7

Having thus given a gen ral description of my invention, I will now, in order to make the matter more clear, refer to the annexed sheet of drawings, which form part of this specification, and in which like characters refer to like parts Figure 1 is a vertical longitudinal sectional elevation of my gas burner together with a portion of the furnace or boiler setting wall into which the end of the burner is inserted, this view being taken on the line II of Fig. 2. Fig.2 is a top plan view of my burner, and Fig. 3 is a front end elevation. I

I Referring now to the characters of reference on the drawings: 1 is the wall of the furnace or boiler setting, 2 a flue or opening therein adapted to receive the combustible gases from my burner, 3 is the outer casing of the burner, 4c the inner end thereof which may be contracted as shown to form a nozzle, 5 is the gas inlet pipe provided with flanged edge 6, whereby it is connected with the gas main or supply pipe 7. 8 is the front flanged edge of my burner construction, 9 is a front plate partially COVGIiIlg the same, 10 is the upper plate or portion of the air conduit, 11 is the bottom plate or portion of the same.

12 and 13 are the side plates or portions of the air conduit,'14 are connections shown as angles for uniting the various portions of the air conduit, 15 is an angle connecting the front plate 9 with the plates 10, 11, 12 and 13, 16 are screw plugs inserted in the front plate to give access when desired to the opening between the air conduit and the other portions of the burner to blow out the dust or for other purposes, 17 are separator bolts which pass through the pipe separators or spacers 18 and firmly brace the top and bottom plates of the air conduit, 19 are guide brackets secured to the bottom plate 11 for the purpose of guiding the regulating rod 29, and 20 are bolts holding two portions of this bracket in position. 21 is a pin or pivot mounted in the end of the regulating rod 29 on which are pivotally mounted the links 22 which are connected to the brackets 23, which in turn are secured to the regulating doors 24, these doors being pivotally mounted on the top and bottom plates by the hinges 25. By means of this construction the doors 2% mav be opened or closed to any extent to control the air supply or maybe more widely opened to diminish the gas supply as indicated by the dotted lines in Fig. 1. 26 is a guide for the outer end of the regulating bar 29 having a slot 27 in the upper portion thereof, in which the bar 29 is adapted to move backward or forward when being guided thereby, and provided with a hand desired, whereby the air regulating doors 24 may be set to any predetermined position. The regulating bar which is connected to the doors is 29 and is provided with a convenient handle 30 for manipulating the same.

31 is the gas inlet space between the outer casing 3 and the top and bottom plates 10 and 11, 32 is the gas space between the cas ing 3 and the side plates 12 and 13, and 33 is the air port or opening which connects the air conduit with the outer air.

Although I have shown and described my invention in considerable detail, I do not wish to be limited to the exact details of construction specified, but I may use such substitutions, modifications or equivalents thereof as are embraced within the scope of my invention as pointed out in the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A gas burner having an outer tubular gas tcasing, an air conduit mounted longitudinally therein and adapted to connect with the outer air, the inner end of said air conduit being provided with a door adapted to be adjusted-to predetermi-ne the size of the air inlet.

2. A gas burner having an outer tubular gas casing, an air conduit mounted longitudinally therein and adapted to connect with the outer air, the inner end of said air conduit being provided-with a pivoted door, and means for adjusting said door to determinethe size of the air or gas inlets.

3. A gas burner having an outer tubular gascasing, an air conduit mounted longitudinally therein and adapted to connect with the outer air, the inner end of said air conduit being provided with a pair of doors adaptedto be adjusted to determine the size of the inlets.

4:. A gas burner having an outer tubular gas casing, an air conduit mounted longitudinally therein and adapted to connect with the outer air, the inner end of said air conduit being provided with a pair of doors and means for adjusting the same to determine the size of the air or gas inlet.

5; A gas burner having an outer tubular gas casing, an air conduit mounted longitudinally therein and adapted to connect with the outer air, the inner end of said air conduit being provided with a pair of doors adapted to be simultaneously adjusted todetermine the size of the inlets whereby a symmetrical passage is provided.

6. A gas burner comprising a tubular casing connected with a source of gas supply, an air conduit mounted substantially concentric therein, one end of which connects with the outer air, the inner end being provided with a pair of opposed doors hinged to opposite sides of said conduit, links piv-- oted to said doors, an operating bar connected to said links which bar extends outwardly of the burner and is provided with means for adjusting the same, whereby the size of the openings may be regulated while maintained substantially concentric with each other.

In witness whereof I hereunto afl'ix my signature.

HERMAN e. SIEBERT.
